1. First you need to download manually the update from microsoft.com and then execute with the switch /x to unpack it (ex. C:\xpupdate).
2. Create update.cmd:

Source code
c:
cd "C:\xpupdate\update"
echo Replace update.inf with update.inf.new
copy update_SP2QFE.inf org_update_SP2QFE.inf /y
copy new_update_SP2QFE.inf update_SP2QFE.inf /y
echo Apply Update
start update.exe /passive /norestart /log:c:\xpupdate\install.log
ping -n 1 -w 5 1.1.1.1>nul
copy org_update_SP2QFE.inf update_SP2QFE.inf /y

3. Copy update_SP2QFE.inf to new_update_SP2QFE.inf (in folder c:\xpupdate\update)
4. On new_update_SP2QFE.inf you need to delete this.

Source code
Condition=AndOp,Prereq.XPAMDInstallBlock.Section

and the end (end of line):

Source code
[Prereq.XPAMDInstallBlock.Section]
PresentOp=CheckReg,HKLM,"SYSTEM\CurrentControlSet\Control\ProductOptions",ProductType,0x00000000
NotEqualOp=CheckReg,HKLM,"SYSTEM\CurrentControlSet\Control\ProductOptions",ProductType,0x00000000,!=,"WinNT"
Display_String="%WrongProductMessage%"

5. Execute update.cmd

You can view install.log to show, if the installation is successfull. A reboot is required.
